"That was how I felt at the time," Carlisle said. "I felt that the players, I felt that the guys did something that was very public but then weren't willing to actually step forward and be accountable for what they did and state the reasons why."

Carlisle was asked if he was still unhappy about the behaviour of the Ferdinand brothers and responded: "I still feel that there's a real reluctance from players to step out on issues, yes. I don't think that they're all s***houses.

"It's a very, very strong word isn't it. But I was very, very angry at the time. I think players should have more courage to stand up for what they believe in and if they feel strongly about something they should speak out and have the courage to do that.

"I didn't say it to them personally, to their faces, but I made it clear in the interviews and in the meetings and in passing on information that [their actions] needed to be explained. I made that clear, and I stated it publicly. There's nothing for me to, I don't think, I don't feel guilty about writing that part. Not at all."
